The two summit peaks of Komagatake, seen here from the NW, are remnants of a scarp formed by prehistoric flank collapse towards the NW. Several episodes of growth and collapse have occurred, with the most recent in 1640 when the flank collapsed towards the E. Photo by Mitsuhiro Yoshimoto, 1995 (Hokkaido University).
